Hello jrperfhorses-gma,
Welcome to the Quickbooks Community! I will be delighted to help you! Invoices work quite differently in QBSE compared to the other QB versions. It is more of a simplified invoicing feature.

Now for the duplicate invoice, follow these steps:
From here, you would need to record the partial payments. You have two options. The first way would be by waiting for it to be downloaded on the Transaction page if it is linked to QuickBooks. The second way would be to add the payments manually.
Please let me know if you need additional assistance. You are always welcomed here! Take care!
